Aku cinta kamu.
Aku = I
cinta = love
kamu = you
You can also replace 'cinta' with 'sayang', which really means the same (love).. Although if you use 'sayang', you can say it to both lover and, say, family and friends. 'Cinta', on the other hand, gives a more serious meaning to the sentence, and is usually just said specially to a lover.
Hope this helps. :)
